For anyone interested in what led up to this, check out my previous thread here. After fixing a stalling problem, my 95 E300D now idles in park at 1100, and at 750 in drive. I've read many posts involving a much similar problem for mid to late eighties models. My car, unlike theirs, doesn't have an idle control valve. In following the advice from an other thread I turned my ac to max while in park to see if the rpms would increase. No change. This supposedly indicates that there is a problem with the idle control module because it is either not sensing the ac turning on or it thinks the ac is always on. I removed the idle control module and the car ran exactly the same. Does this mean that my car has been idling manually the whole time? Does this conclusively point to a bad idle control module? Where/how can I test the icm wires or even the unit itself for continuity? I had removed the ovp to test my previous stalling problem, but I'll try it again for this.
